Yes the "text" book definition is a low volume down bar closing mid to high, confirmed by an upbar but I'm pretty sure that I've read Jako post that in real life the tests aren't text book, and not to get too hung about the shape and volume but to pay attention to the intent.
(will remove if speaking out of turn )
(and the reference to a text book example was to the uptrend with the tests - not the tests themselves per se)
)
